After the protrusion 412 passes through the installation notch 52, the annular structure is rotated in a preset direction, so that the installation notch 52 is rotated to avoid the protrusion 412, and the connecting assembly is in an assembling state. Thus, on one hand, the first connecting structure 40 and the second connecting structure 50 are easier to disassemble and assemble, and the operation difficulty of a user is reduced; on the other hand, the installation notch 52 is arranged to avoid the convex part 412, so that the convex part 412 can pass through the concave part 51 and is limited and stopped by the annular structure, and the connection reliability of the connecting assembly is improved.

Specifically, the mounting notch 52 is arc-shaped, and during the process of assembling the cover 10 with the base 20 and the top cover 30, the protrusion 412 is disposed corresponding to the mounting notch 52, so that the protrusion 412 is inserted into the annular structure through the mounting notch 52. And then. The clothes cover 10 is rotated along the preset direction, so that the installation notch 52 is rotated to the position avoiding the convex part 412, the connecting assembly is in an assembling state at the moment, the convex part 412 can be limited and stopped with the annular structure, the annular structure is prevented from being separated along the thickness direction of the annular structure, and the clothes cover 10 is assembled with the base 20 and the top cover 30. When the clothes cover 10 needs to be detached from the base 20 and the top cover 30, the annular structure is rotated along the direction opposite to the preset direction, so that the annular structure is rotated to the arrangement that the installation notch 52 corresponds to the convex part 412, at the moment, a user can pull the annular structure along the height direction of the clothes cover 10, so that the clamping protrusion 41 is withdrawn out of the annular structure, and the clothes cover 10 is detached from the base 20 and the top cover 30.

It should be noted that the structure of the second connecting structure 50 is not limited thereto, and can be adjusted according to the working condition and the use requirement. Alternatively, the second connecting structure 50 is a ring-shaped structure, and a deformation space is formed between the two catching protrusions 41. Like this, at the in-process that clothing cover 10 and base 20 and top cap 30 assembled, the operation annular structure to make two joint arch 41 move towards each other, until the annular structure cover is established on joint arch 41, coupling assembling is in the assembled state this moment, convex part 412 can be with the spacing backstop of annular structure, with prevent that annular structure from deviating from along its thickness direction, and then realized the assembly of clothing cover 10 and base 20 and top cap 30.

In this embodiment, the mounting notch 52 is located between at least two adjacent snap projections 41 when the connection assembly is in the assembled state. Thus, after the clothes cover 10 is assembled with the base 20 and the top cover 30, the arrangement can prevent the clamping protrusion 41 from falling out of the concave part 51 to influence the connection stability of the connecting assembly, and the structural stability of the clothes dryer is improved.

Specifically, the installation notch 52 is located between two adjacent clamping protrusions 41, so that the structure of the installation notch 52 is simpler, and the installation notch is easy to process and implement, thereby reducing the processing cost of the second connecting structure 50.

Optionally, one mounting notch 52; alternatively, the number of the mounting notches 52 is plural, and the plural mounting notches 52 are provided corresponding to the plural catching projections 41. Thus, the number of the installation notches 52 can be selected more flexibly by the arrangement, different use requirements and different working conditions can be met, and the processing flexibility of workers can be improved.

In this embodiment, the number of the installation notches 52 is one, so that the structure of the second connecting structure 50 is simpler, the processing and the implementation are easy, and the processing cost of the connecting assembly is reduced.

It should be noted that the number of the installation notches 52 is not limited to this, and can be adjusted according to the working condition and the use requirement. Alternatively, there are two mounting notches 52, and two mounting notches 52 are provided in one-to-one correspondence with the two catching projections 41.

In this embodiment, the extension 411 is an arc-shaped plate, and a convex portion 412 is disposed on an end of the arc-shaped plate, and the arc-shaped plate is disposed coaxially with the annular structure. Like this, at the user's in-process of rotating the loop configuration, above-mentioned setting is avoided taking place between loop configuration and the extension 411 to move and is interfered and influence coupling assembling's dismouting, has further promoted coupling assembling's connection reliability.
